BACKGROUND Endothelial dysfunction plays a crucial role in heart failure (HF), but the association between peripheral microvascular endothelial function assessed by reactive hyperemia peripheral arterial tonometry (RH-PAT) and prognosis remains unknown in HF with reduced left ventricular (LV) ejection fraction (HFREF). We prospectively investigated the association between peripheral microvascul...
different types of high-fat (Hf) diets are used to study diet-induced obesity (dio) in rodents and this has led to different phenotypes. this study assesses whether different Hf diets differentially affect striatal dopamine d 2/3 receptor (drd 2/3 ) availability, as decreased striatal drd 2/3 availability has been implicated in obesity in relation to reward deficiency for food. thirty rats were...
BACKGROUND Although similar to cancer patients regarding symptom burden and prognosis, patients with heart failure (HF) tend to receive palliative care far less frequently. We sought to explore factors perceived by cardiology, primary care, and palliative care providers to impede palliative care referral for HF patients. METHODS AND RESULTS We conducted semistructured interviews regarding (1)...
BACKGROUND Population-based research on heart failure (HF) is hindered by lack of consensus on diagnostic criteria. Framingham (FRM), National Health and Nutrition Examination Survey (NHANES), Modified Boston (MBS), Gothenburg (GTH), and International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM) code criteria, do not differentiate acute decompensated heart failure (...
Exercise training (ExT) normalizes the increased sympathetic outflow in heart failure (HF), but the mechanisms are not known. We hypothesized that ExT would normalize the augmented glutamatergic mechanisms mediated by N-methyl-d-aspartic acid (NMDA) receptors within the paraventricular nucleus (PVN) that occur with HF. Four groups of rats were used: 1) sham-operated (Sham) sedentary (Sed), 2) S...
The PF3H+ ion is prepared as PF3H+.SbF6-.HF by protonation of PF3 with HF/SbF5 at low temperatures in anhydrous HF. Crystals are obtained directly from this solvent. A crystal structure determination shows the presence of a pseudo-tetrahedral PF3H+ ion with a mean P-F distance of 148.7(2) pm, a P-H distance of 122(4) pm, and a mean PF2 angle of 106.1(1) degrees. Raman spectra were recorded of P...
To cite: Catchpole K. BMJ Qual Saf 2013;22:793–797. INTRODUCTION Human factors (HF) is a term many involved in healthcare delivery are now familiar with, even though a decade ago most had never heard of the concept. The majority of clinicians and healthcare improvement specialists have learned of HF through a particular branch of practice that derived from aviation and arose from the need to ad...
The distribution coefficient (Kd) of Rf on ion exchange resins at various HNO3/HF concentrations had been studied [1]. Rf was eluted at higher HF concentrations from CIX than Zr and Hf and rather resembled Th. Up to 1 M HF, Rf was not retained on the AIX also resembling its pseudo-homolog Th. Th is known to form no anionic fluoride complexes, while Zr and Hf are forming complexes of the type [M...
Heart failure (HF) is a complex clinical syndrome affecting more than 23 million people world-wide.1) The incidence of HF is associated with age, and it has remained stable in the past several decades. With the aging of society, the prevalence of HF is expected to rise, and indeed, in 1994 the prevalence of HF was 90 per 1000 beneficiaries and increased to 121 per 1000 beneficiaries in 2003 in ...
PURPOSE In the present study, we investigated the effect of exercise and arginine on the inflammatory makers and Cu-Mn superoxide dismutase (SOD) expression in the aortas of high-fat-induced obese rats. METHODS Fifty 6-month-old male Sprague-Dawley rats were randomly assigned as follows: HF-Con: high-fat diet, HF-Ex: high-fat diet and exercise, HF-Ex+A: high-fat diet and combined exercise and...
